PAPER-Fascino MACHINE.

SPECIFICATION forming part of Letters Patent No. 83,906, dated August Q8, 1883.

A pplicntion tiled Ap1il26,1881. (Model.)

To @ZZ whoml t may concern:

Beit known that I, FRANK H. LAUTEN, of the city, county7 and State of New York, have invented a new and Improved Paper-Feeding Machine, of which the following is a specification.

1 My invention relates to improvements in paper feeding machines for printing -presses, ruling-machines, paper box and bag machines, folding-machines, and analogous machines th at require to have the paper fed regularly and in single sheets, and in such a manner as to cooperate with the other machinery that receives the sheets.

The invention is an improvement on the paper-feeding machine for which Letters Patent No. 223,742, of January 20, 1880, were granted to me.

In the accompanying` drawings, Figure l is a cross-sectional elevation of my improved paper-feeding machine on the line as rv, Fig. 3. Fig. 2 is a cross-sectional elevation of the same on the line y y, Fig. 3. Fig. 3 is a front elevation of the same.`

Similar letters of reference indicate corresponding parts.

Ashaft, D, is journaled in the standards C, and is rotated by means of the crank X, or any other suitable device for the same purpose.

A knoclzer, F, consisting of two curved con- -nected bars, F, provided with bifurcations or hooks F2 at the upper ends, straddles the shafts D and E, the bifurcation or hook FZ passing over the latter, as shown in Fig. 1 The knocker is provided with two lateral projections or studs, g g, directly over the center of the shaft D,` in such a manner that when the shaft D rotates the semi-annular cams G of the shaft D will pass under the studs g and raise them, and consequently the knocker will be raised also; but as soon as the other end of the cam G has passed from under the projections g the kuocker will drop suddenly.

Crank-wheels H are mounted on the ends of the shaft D, and are connected by a rod, L, eccentrically pivotcd thereto, with a rocking shaft, M, which slides in the horizontal slotted guides N.

A An angularly-bent arm, R, is attached to 5o the shaft M, and the angular end of this arm slides along thelower edge of alongitudinally adjustable plate, a, below the slotted guide N, andwithin a vertically-adjustable horizontal U-shaped strip, t, resting on an adjustable screw, t. By means of the plate u, with a beveled edge toward the knocker, the length of the distance that the feeder attached to the shaft M is to traverse in a raised position is regulated, for by the plate u the arm R is lowered or depressed, and consequently the feeder O, which projects from the shaft M in the opposite direction, is raised.` The pressure of the feeder on the paper can be regulated by means of the screw i.

Two or more rods, p, are attached to the shaft M by means `of screws or other devices, and to the 'outer ends of these rods-f-that is, to the ends toward the knocker-the feederO, consistin g of a casing containing a rubber strip or block, is attached. As Vthe shaft M rocks and slides, the feeder O will also rock and slide, in a manner that will be fully described hereinafter.

An apron, 112, is pivotcd to the standards C C, in-such a manner that its outer edge will rest upon the inner edge of the pack of sheets. The outer or swinging edge of this apron?)2 is drawn upward by a spring, lf, attaclied to the shaft E, parallel with the shaft D, slightly above it. The outer or swinging edge of this apron b2 is also connected by a rod, d, with one end of a lever, f, pivotcd on the shaft E, the other end of which lever rests upon a semiannular cam, V, of the shaft D.

Two rollers, a a, are j ournaled in the upright C O, in such a manner that a sheet that slides up the apron a2 will slide between them 'upon cordsc o, passing to other parts of the machine.

A plate, Z, connects the bottom of -the knoeker-bars F', and to the inner edge of this plate Z a flap, WV, is pivotcd, which is drawn upward by a spring, NV', attached to its outer edge, and to a short bar, o', connecting the knocker-bars F. A rod, k, rests upon theflap W, and passes through two plates, o'Z o2, connecting the knocker-bars F/ and guiding the rod It. The swinging end of a lever, m', pivoted on a standard, s, of the plate Z, rests upon the upper end of the rod if, and a cam, E, isY 10o so mounted on the shaft D that it will depress the lever m and the rod 7c when the shaft D rotates, thereby overcoming the power of the spring W, and throwing the flap W upon the stack of sheets, whereby the upper sheet is smoothed, &c.

The paper-carrier A is provided with lateral projections fitting in between the guides B B on the inner sides of the standards C C. The paper-carrier A is suspended from two chains, Y Y, passing over pulleys B B to the top of the standards C C, and the other ends of these chains are attached to powerful springs C, attached to the base of the machine. The paper-carrier and the paper thereon are thus pressed against the under side of the plate Z of the knocker with considerable force.

An angular latch-bar, D2, with a V-shaped recess in the end of the short arm, is pivoted to the outer edge of each standard C, and is used to hold the paper-carrier A in the lowered position, as shown, when a fresh stack of paper is to be placed upon the carrier. y

P' represents the stack of sheets of paper. Segmental guides k are attached to the shaft D over the cams G,Aand hold and guide the knocker when the studs g are not on the cams G. y

The rollers a a move with such rapidity that sheets of any desired size can be drawn from the stack during the time the feeder is raised until it is lowered again.

The operation is as follows: The paper-carrier A is lowered by some suitable levers, and is locked in position by means of the latches D", as shown in Fig. 3, upon which the sheets P are placed upon this carrier. The chains Y and the 'springs C draw the carrier upward and press the sheets against the under side of the plate Z. If the several parts Yof the machine are in the position shown in Figs. l and' 2 and the shaft D is rotated in the direction of lthe arrow x, the feeder O will move in the di rection of the arrow g, and as the knockerplate Z rests upon the uppermost sheet, this sheet will be bulged or lapped, as shown, and its end will be drawn out from under the apron b2, which has been drawn upward or raised by the spring b; but this apron is then lowered by the actionI of the cam Y on the lever j' and rod d', and the feeder O moves in the inverse direction of the arrow y', and draws the sheet up over the apron b2 inbetween the rollers a a, which seize it and draw it from the stack, for in the meantime the linocker Fhas been raised by the action of the cams G on the projections g, thus permitting the sheet to be withdrawn from under the knocker. By the action of the guideplate a or the arm R of the rocking shaft M the feeder O is raised from the paper when the shaft M moves backward; but when the shaft M moves forward, the feeder O is pressed upon the paper and bulges the upper sheet, which iscarried off, all in the same manner as described above. As soon as the rollers a a have drawn the sheet from under the knocker the flap W is forced down bythe action of the cam E on the lever m, and the rod k smoothing the rest of the sheets on the stack.

Having thus fully described my "invention, I claim as new and desire to secure by Letters Patent* l. In an automatic paper-feeding machine,

the combination, with the paper-carrier A, the rocking and reciprocating feeder O, and the apron b2, of the knocker F and the flap W, connected to said knocker, substantially as shown and described.

2. In an automatic paper-feeding machine, the combination, with the feeder O andthe reciprocating shaft M, of the guide-arm R and the guide-plates u and t, substantially as herein shown and described, and for the purpose set forth.

3. In an automatic paper-feeding machine, the combination, with the knocker F, provided with'studs g g, of the semi-annular cams G on the shaft D, and of the segments 7c on the shaft D above the cams, substantially as herein shown and described, and for the purpose set forth.`

4. In an automatic paper-feeding machine, the combination, with the knocker-bars F, of the base or bottom plate, Z, the ilaps W, the spring WV', the rod 7c, the lever m', the standard s, and the arm E on the shaft D, substantially as herein shown and described, and for the purpose set forth.

5. In an automatic paper-feeding machine, the combination, with the bent and forked bars FF, resting on shafts and connected by transverse bars and plates, of the projections or studs g and the cams G on shaft D, as and for the purpose specified.
